A missile of magical energy darts forth from your fingertip and strikes its target, dealing 1d6+1 points of force damage.

The missile strikes unerringly, even if the target is in melee combat or has less than total cover or total concealment. Specific parts of a creature can’t be singled out. Inanimate objects are not damaged by the spell.

You gain an additional missile at every 2 caster levels (2 missiles at 4th level, 3 at 6th, 4 at 8th, 5 at 10th, etc), to a maximum of 10 missiles. If you shoot multiple missiles, you can have them strike a single creature or several creatures. A single missile can strike only one creature. You must designate targets before you check for spell resistance or roll damage. Each missile is seen as a different attack so for missile has to be rolled for.
